The original series has a certain pacing and development for their relationship. But in the fanfiction, the Arrancar aspect of Ichigo could speed things up. For example, Arrancar Ichigo might have a more primal, possessive side towards Rukia. This could lead to a more passionate and tumultuous relationship. Also, they would face different external threats and challenges because of Ichigo's new form, which would force them to rely on each other in new ways and thus change how their relationship develops.
It might develop through a series of battles and near - death experiences. For instance, if they are in a fight against a common foe and Hollow Ichigo saves Rukia's life. This act could make Rukia reevaluate her view of him. Similarly, if Rukia shows kindness or understanding towards Hollow Ichigo in a moment when he least expects it, it could thaw his cold exterior towards her, gradually building their relationship.
In the original series, they have a rather casual acquaintance. But in fanfiction, their relationship could develop into a friendship based on mutual respect. Bulma could teach Beerus about Earth's technology, and Beerus could share some of his knowledge of the universe with her.
If they travel to a time when the Quincy and Soul Reapers were at peace, their relationship could develop in a more carefree way. They could explore the different cultures together without the threat of war. However, if they go to a time when there was a great divide between the two groups, they might have to hide their relationship or even be on opposite sides at first. But as they discover the truth behind the conflict, they could work together to bridge the gap, which would enhance their relationship. In a time closer to their own but with some changes, like if Ichigo was more powerful from the start, Rukia might have a different kind of admiration for him, and their relationship could shift from a more mentor - student type to a more equal partnership faster.
The original series shows a relationship that develops in a more traditional way within the context of a battle - filled anime world. In the vampire fanfiction, their relationship could develop in a more supernatural - themed way. Vampire Vegeta might use his powers to protect Bulma in ways that are completely different from his Saiyan abilities in the original. Their relationship could also be influenced by the vampire lore. For example, if there are vampire clans or hierarchies, Vegeta's position in that could affect how he and Bulma interact with the world around them, and this would be a significant departure from the relatively straightforward relationship development in the original series.
In the original series, Naruto and Obito have a complex relationship mainly based on opposing sides. In a fem Naruto and Obito fanfiction, their relationship could start with more empathy. Fem Naruto might be more understanding of Obito's pain from the start. Maybe she would approach him in a different way, not just as an enemy but as someone who can be redeemed. For example, instead of fighting him right away, she could try to talk to him and get to his heart.
In the original series, Naruto and Shizune don't interact much. In a fanfic, their relationship could develop in a more friendly way. For example, they could start training together. Naruto could learn some medical ninjutsu from Shizune, and Shizune could learn some of Naruto's unique combat techniques.
In the original series, their interactions are mainly about team - up and mutual support. But if we consider the yandere Oliver Queen x Barry Allen fanfiction, Oliver's possessiveness would change the dynamic completely. He would be overly protective and might even prevent Barry from using his powers to their full extent if he thinks it's too dangerous. This could lead to Barry resenting Oliver, which is very different from the positive and collaborative relationship they share in the show.
In the original series, Naruto and Ino don't have a very close relationship. But in a Smart Naruto x Ino fanfiction, Naruto's intelligence could make him more aware of Ino's potential as a partner. He might approach her more directly, leading to a quicker development of their relationship. Instead of just being comrades, they could become confidants early on.
Well, in the original series, they were mostly adversaries. In fanfiction, they could start as adversaries but then gradually develop an understanding. For example, they might find out they have a common enemy who is manipulating events behind the scenes to keep them at odds.
Well, in the original series, their relationship was more of a friendly rivalry. But in the fanfiction where they're engaged, it would be more about building a life together. They would have to communicate better, share their dreams and fears more openly. For example, Sasuke would have to be more open about his past traumas and Naruto would have to be more understanding. Their relationship would also be more about compromise, like deciding where to live, whether in Konoha or somewhere else.
